Currently the Hudson maven job is failing due to a maven dependency problem. Besides that
I saw that the emai-ext is throwing an NPE when retrieving the content:

Steps to reproduce:
1. Create a maven job with email-ext plugin enabled
2. Create a pom.xml that depends on a maven lib that doesnt exist (to provoke the error)
3. Build the job

Expected outcome:
A mail is sent according to the email-ext configuration

Actual outcome:
NPE in console:
started
